About the Stm32pe midi PCB

Stm32pe midi is an open source STM32 PCB design by udu3324, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 307 × 46.1 mm, with 135 components from 26 distinct parts.

Its main chip is the STM32H743VIHX, from the STM32 family. Other key parts include the LM3940IMPX-3.3/NOPB, TMAG5273, TPD2EUSB30, TCA9548A and TLC5940PWP. By type, the board carries 41 capacitors, 31 ICs, 30 diodes, 26 resistors, 5 connectors and 2 switches.

It belongs with the audio and keyboards designs in this gallery.

From the project

a midi controller using the mpe protocol to create more expressive music

An expressive midi controller based on the stm32 ecosystem. It uses the MPE midi protocol to pass through signals that act as gestures/effects including velocity/note to any music DAW. (like ableton)

- Uses the powerful STM32H7 - Uses USB-C OTG to connect to a device - Has per key PWM leds for indication - Low profile/one sided pcb design - Small key footprint for compactness - Two octaves + extra key before an octave

Stm32pe midi: common questions

What microcontroller does the Stm32pe midi use?

The Stm32pe midi is built around the STM32H743VIHX, from the STM32 family.

How big is the Stm32pe midi PCB?

The Stm32pe midi measures 307 × 46.1 mm, has 4 copper layers and is 1.599978 mm thick.

How many components are on the Stm32pe midi?

135 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Stm32pe midi design files?

From the udu3324/stm32pe-midi repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Stm32pe midi design in my own project?

Yes, under the terms of its GPL-3.0 license, which udu3324 chose for the repository.

Can I test firmware for the Stm32pe midi without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
